There are two threaded rods 304, and a second limit plate 12 is provided on the threaded rod 304. In order to limit the moving distance of the slider 305 and facilitate the addition of the desulfurization catalyst, one end of the threaded rod 304 is connected to the processing box 1 through a bearing, and the other end is connected to the output end of the driving motor 6.

In addition, by setting the feeding mechanism 5, while removing the used desulfurization catalyst, the sealing plate 503 can be opened through the pulling plate 504, and the desulfurization catalyst inside the feeding trough 502 can be added to the inside of the guide trough 501. When the scraper 306 moves, the desulfurization catalyst inside the guide trough 501 can be driven to fall onto the metal filter plate 2, and the desulfurization catalyst is flattened through the bottom of the guide trough 501 to ensure that the desulfurization catalyst is evenly distributed.
